You’ll find this in the anthology, Deep Navigation.
In this short we’re off to an Antartic research station, in Marie Byrd Land: oh yeah, you get to learn about real stuff with Alastair.
Anyway, someone’s been playing with quantum entanglement and has totally messed all kinds of things up for the people at “Byrd Land Six”, and also on the Moon, where the other half of the entangled pair is residing.
Once again, super good sci-fi from a real physicist: we like!
Next up in the Alastair Reynolds timeline is Spirey and the Queen.
